Winding displacement lifting type fireproof roller shutter
The invention provides a winding displacement lifting type fireproof roller shutter. The winding displacement lifting type fireproof roller shutter comprises a shutter surface, a lifting mechanism and guide rails; the winding displacement lifting type fireproof roller shutter is characterized in that the lifting mechanism is formed by a fireproof electric hoist, one or multiple rolling shafts, a transmission mechanism, universal couplers which are connected between every two adjacent rolling shafts, multiple fixed pulleys which are arranged on a top support of a building door opening, multiple rope wheels which are arranged on the rolling shafts and multiple lifting steel wire ropes which are horizontally and uniformly distributed on the shutter surface; the top end of the shutter surface is fixedly arranged on the top support of the building door opening; one end of each lifting steel wire rope is fixedly arranged at the bottom part of the shutter surface, and the other end of each lifting steel wire rope can ascend along the shutter surface and is fixedly arranged on the corresponding rope wheel by passing through the corresponding fixed pulley. Compared with an existing fireproof roller shutter, the winding displacement lifting type fireproof roller shutter is adapted to a large-span fireproof zone, a curved fireproof zone and a relatively-complex installation environment.
